2 Kings 14:5-7

New Revised Standard Version Catholic Edition

⁵ As soon as the royal power was firmly in his hand he killed his servants who had murdered his father the king. ⁶ But he did not put to death the children of the murderers; according to what is written in the book of the law of Moses, where the Lord commanded, “The parents shall not be put to death for the children, or the children be put to death for the parents; but all shall be put to death for their own sins.”

⁷ He killed ten thousand Edomites in the Valley of Salt and took Sela by storm; he called it Jokthe-el, which is its name to this day.
